SASH-OPERATING MECHANISM.

Specification of Letters Patent.

Patented Aug. 7, 1906.

Application filed October 25, 1905. Serial No. 284,319.

Other objects of the invention will appear I in the general description.

I will describe a sash-operating mechanism embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanyingdrawings, forming apart of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is an inside elevation of a windowcasing and sash therein with an operating mechanism embodying my invention. Fig. 2 is a section thereof on the line 2 2 of Fig. 3. Fig. 3 is a top plan, and Fig. 4 is a side elevation.

Referring to the drawings, 1 designates a window-casing in which are the u per and lower sashes 2 and 3, slidable vertica ly. Arranged in the casing at one side is a weight 4, from which a sash-cord 7 extends upward through an opening in the top plate of the easing, thence over a ulley 8 at one side, and over a pulley 9 at tlie opposite side, to a connection with the upper portion of the upper sash, as clearly indicated in Fig. 2. From the lower portion of the weight 4 a cord 10 passes around a pulley 11 and thence upward to connection with the lower portion of the upper sash 2.

In my invention I provide a means exteriorly of the window-casing by which the sash may be conveniently raised and lowered. As here shown, this means consists of a drawline 12, which is connected to the weight at the upper and lower ends, the upper stretch of the draw-line passing over a pulley 13, arranged within the case, and thence through an opening in the front plate of the casing, over a pulley 13 thence down at the other side of the casing side board around the pulleys 14 and 14. The upper portion of the upper sash at the side opposite its connection with the sash-cord 7 is connected to a cord 5, which passes over a pulley 6, arranged in the window-casing, and connects with the upper end of the weight 4. As shown in the drawings, the cords 5 and 7 are connected or continuous and pass around a pulley 5 in the.

weight, thus permitting the weight to adjust itself should this cord expand or contract. The lower sash is provided with a weight similar to the weight 4, and the connections are also similar that is, from the weight for the lower sash a cord 15 passes upward and around pulleys 16 and 17. An exterior draw line or cord 18 connects with the weight for the lower sash and asses over pulleys 1.9 and 20, arranged in t e side of the windowcasing opposite the pulleys 13 and 14*, as

indicated inFig. 1.

By my invention it is evident that the sash may be operated without a person. lacing his hands on the sash, and it will be ound very convenient when windows are at a considerable distance up from the floor, as the drawline may be carried down to any desired point.

Having thus described my invention I claim as new and desire to secure by Letters Patent 1. The combination with a window-casing and a sash therein, of a weight arranged in the casing, pulleys at the upper' portion of the casing, a cord extended from the weight, over said pulleys to connection with the sash at one side, a cord extended from the weight, over a pulley to connection with the sash at the opposite side, a pulley at the lower portion of the casing, a cord extended from the lower portion of the weight around the lower pulley and connecting with the lower portion of the sash, and an operating device connecting with the weight and having a portion extended exteriorly of the casing.

2. The combination with a window-casing and a sash therein, of a weight arranged in the casing, pulleys at the upper portion of the casing, a cord extended from the weight over said pulleys to connection with the sash at one side, a cord extended from the weight over a pulley to connection with the sash at the opposite side, a pulley at the lower portion of the casing, a cord extended from the lower portion of the weight, around the lower pulley and connecting with the lower portion of the sash, uiieys arranged in the cas- In testimony whereof I have signed my mg above and be ow the Weight, and a drawname to this specification in the presence of line having its ends connected to the upper two subscribing witnesses.

and lower ends of the Weight and passing GEORGE P. BULL. 5 over said last-named pulleys, and having a Witnesses:
